SNAP-SWITCH.

- Application filed February 20, 1908, Serial No. 416,933.

To all whom 'it may concern:

Be it known that I, CHARLES J. KLEIN, a citizen of the United States,and resident of the city of New York, in the county of New York andState of New York, have invented certain new and useful Improvements inSnap-Switches, of which the following is a specification.

This invention relates to switches adapted for use with electricalcircuits.

The object of this invention is to )rovide' ant or socket switch, whichis adapted for use in the usual manner to open and close the circuit bysimply pressing a button.

In the drawings like parts have been given similar reference numbers inthe several views.

Figure l is a sectional side elevation of a simple form of switch in itsopen position. lfig'. Q is a. side elevation of one-half of the switchshown in Fig. 1. Fig. 3 is a side elevation of the operative parts ofthe switch shown in Fig. 1 in closed position. Fig. el is a similar viewto Fig. 3, showing a modification of the operating mechanism.

At 1 and "2 are shown the two half-sections of a casing, preferably ofinsulating material, such as porcelain, in which the switch proper maybe mounted. These halfsections are secured together by any suitablemeans and may be separated to permit of the assembling of the switchparts and also for making the wire. connections.

At 3 is shown a movable member or cam, 1.)refera bly of insulatingmaterial, mounted in the casing l and 2- so that the same may be movedback and forth by the alternate pressure of the finger on one end or theother of this member which projects through the casing as shown. Thecentral portion of this cam or movable member 3 is so formed as toprovide oppositely inclined surfaces on either side of a line transverseto the axis readily turned on the member 3.

thereof. These surfaces, for the convenience of manufacture, arepreferably conical in form, as shown at 4 and 5, and may be Stops whichmay take the form of stop rings 30, 31 are secured to the member 3 andengage the casing to limit the movementof the cam. They form stopsindependent ofqthe cam surfaces.

A switch blade 6 is carried upon the movable member 3 and alternatelyrides upon the conical portions 4 and 5 as the member 3 is moved, in themanner hereinafter de scribed. Line terminals 7 and 8 are so positionedas to be engaged by the switch blade 6 when in its closed position andso close the circuit 'therethrough.

A resilient member 9 in the form of a coil spring surrounds the taperedportions 4 and 5 of the movable member This resilient member forms thesecond movable member of the combination. The casing is so formed thatthe lower portion of this spring is substantially held stationary withrelation to the movable member 3, but another portion of the spring iscaused to move at an accelerated speed with relation to said cam. Theends of this coiled spring are attached to a pin 10 which is carried atone end of a third movable member 11, which constitutes a means forgiving an impact to the switch blade. This member 11 is positioned in atriangular shaped recess in the switch blade (5 in such a manner as tohave a bodily movement with relation to the switch blade and transverseto the axis thereof, theuppcr end thereof being swung forward and backas the device is operated.

Assuming the parts to stand in the open position, as shown in Fig. 1,the slidmg member 3 being. pushed to the right shifts the point uponwhich the switch blade 6 rests causing the same andthe spring 9 to rideover the high central portion of the member 3 and upon passing thispoint to move quickly down upon. the opposite inclined portion 4. Asthis takes place the movement of the sprin 9 causes the member 11 tobeswung quickly to the opposite side of the recess in the blade 6 and theimpact or blow produced accelerates the movement of the switch blade 6and also insures the same being positively and quickly brought intoengagement with the line terminals 7 and 8, thus insuring a more perfectcontact and closing of the circuit.

To open the switch the sliding member 3 is moved in the oppositedirection and the inclined portions 4- and 5 cause a similar movement ofthe switch blade and associated parts in the reverse direction. Themember 11 is swung in the opposite direction by this movement and theimpact or blow caused by the same striking the opposite side of therecess in the blade 6 facilitates the releasing of the same from itsengagement with the line terminals 7 and 8 and also accelerates themovement thereof and assists in producing the quick breaking oil-thecircuit which is one of the desired results in switches of this nature.

In the modification shown in Fig. 4: the operation of the several partsis similar to that just described. The coiled spring 9 is attached to apin 12 which is positioned in a slot 13 in the switch blade 6. The moement of the sliding member 3 causes the pin 12 to be moved withrelation tothe switch blade, transversely to its axis and quickly I fromone end to the other of the slot 13, ac-

celerating and assisting the operation of the device in producing thequicltopening and closing of the circuit. The operation of this form ofdevice is similar to that just described and will be readily understoodwithout further explanation.

It will be understood that the movementof the m mber 3 may beaccomplished in various ways depending upon the use to, which the deviceis to be put.

It will benoted that the straight line movement of the operating member3 is transformed into a swinging movement of a third member about apivot and that the pivotal point at which the third member is supportedis also moved as the switch blade is caused to operate. This producesthe accelerated swinging movement which has many advantages for devicesof this nature.

It will be understood that my invention may be applied to devices forvarious uses other than the one shown and described herein and that I donot confine myself to this or any other particular embodiment of thesame. 1t is further and particularly to be understood that I do notconfine myself to any specific details of construction.

As many changes could be made in the above construction and manyapparently widely difierent embodiments of my invention designed withoutdeparting from the scope. there f, I intend that all matter mm- '1 ainedin the above description or shown in the accompanying drawings shall beinterprettd as illustrative merely of an operative embodiment of myinvention and not in a limiting sense.
